In real life…

Hikari (which means Light) is the name of a high-speed train service running on the Tōkaidō and Sanyō Shinkansen “bullet train” lines in Japan. Slower than the Nozomi but faster than the Kodama, the Hikari is the fastest train service on the Tōkaidō and Sanyō Shinkansen that is covered in the Japan Rail Pass.
